Grubs up! Berlin tackles American crayfish invasion by putting them on our plates

Last summer, daily sightings of crayfish in the German capital were being reported in the city centre. Now, with the crustaceans rapidly multiplying, health authorities have offered a mouth-watering solution to reduce their numbers.

A small family-run fishery in Berlin's Spandau district was granted permission to catch the red crustaceans for human consumption last week.

Over 1,600 crayfish found themselves in fishing nets in the first few days alone, said Derk Ehlert, a wild fauna expert from the Senate's environmental department in Berlin.

After health officials gave the all-clear about a week ago, fishermen jumped at the opportunity and immediately started catching them, intending to sell them to restaurants and private individuals.

“But we expect declining quantities over the course of the year,” Ehlert added.

Large populations of the red swamp Louisiana crayfish, which grow up to 15 centimetres in length and are originally from parts of the southern US and northern Mexico, came to the attention of visitors and locals in Berlin’s Tiergarten park in August.

They were spotted scuttling across streets and pathways and have since grown in significant numbers in lakes in and around the park.

Environmental authorities gave fishermen permission to catch the crayfish for a period lasting to the end of the year after assessing that they did not contain dangerous levels of toxins or heavy metals.

“No limits have been exceeded” with regard to pollutants, Ehlert said during examination of the animals.

But grabbing and catching one yourself is “prohibited,” the expert warned, as this would be considered poaching.

If you are able to get your hands on one of the crustaceans from the fishery, a traditional way of cooking them in the American south – where it’s considered a delicacy – is to place them live into a pot of boiling water seasoned with cayenne pepper, salt, lemon, garlic, onions and bay leaves.

Boil the crayfish for just under five minutes and let them stand covered for 5-20 minutes, depending on your preference. Then serve with sweetcorn and potatoes.

EXPLAINED: Berlin’s latest Covid rules

In response to rapidly rising Covid-19 infection rates, the Berlin Senate has introduced stricter rules, which came into force on Saturday, November 27th. Here's what you need to know.

The Senate agreed on the tougher restrictions on Tuesday, November 23rd with the goal of reducing contacts and mobility, according to State Secretary of Health Martin Matz (SPD).

He explained after the meeting that these measures should slow the increase in Covid-19 infection rates, which was important as “the situation had, unfortunately, deteriorated over the past weeks”, according to media reports.

Essentially, the new rules exclude from much of public life anyone who cannot show proof of vaccination or recovery from Covid-19. You’ll find more details of how different sectors are affected below.

Shops
If you haven’t been vaccinated or recovered (2G – geimpft (vaccinated) or genesen (recovered)) from Covid-19, then you can only go into shops for essential supplies, i.e. food shopping in supermarkets or to drugstores and pharmacies.

Many – but not all – of the rules for shopping are the same as those passed in the neighbouring state of Brandenburg in order to avoid promoting ‘shopping tourism’ with different restrictions in different states.

Leisure
2G applies here, too, as well as the requirement to wear a mask with most places now no longer accepting a negative test for entry. Only minors are exempt from this requirement.

Sport, culture, clubs
Indoor sports halls will off-limits to anyone who hasn’t  been vaccinated or can’t show proof of recovery from Covid-19. 2G is also in force for cultural events, such as plays and concerts, where there’s also a requirement to wear a mask. 

In places where mask-wearing isn’t possible, such as dance clubs, then a negative test and social distancing are required (capacity is capped at 50 percent of the maximum).

Restaurants, bars, pubs (indoors)
You have to wear a mask in all of these places when you come in, leave or move around. You can only take your mask off while you’re sat down. 2G rules also apply here.

Hotels and other types of accommodation 
Restrictions are tougher here, too, with 2G now in force. This means that unvaccinated people can no longer get a room, even if they have a negative test.

Hairdressers
For close-contact services, such as hairdressers and beauticians, it’s up to the service providers themselves to decide whether they require customers to wear masks or a negative test.

Football matches and other large-scale events
Rules have changed here, too. From December 1st, capacity will be limited to 5,000 people plus 50 percent of the total potential stadium or arena capacity. And only those who’ve been vaccinated or have recovered from Covid-19 will be allowed in. Masks are also compulsory.

For the Olympic Stadium, this means capacity will be capped at 42,000 spectators and 16,000 for the Alte Försterei stadium. 

Transport
3G rules – ie vaccinated, recovered or a negative test – still apply on the U-Bahn, S-Bahn, trams and buses in Berlin. It was not possible to tighten restrictions, Matz said, as the regulations were issued at national level.

According to the German Act on the Prevention and Control of Infectious Diseases, people have to wear a surgical mask or an FFP2 mask  on public transport.

Christmas markets
The Senate currently has no plans to cancel the capital’s Christmas markets, some of which have been open since Monday. 

According to Matz, 2G rules apply and wearing a mask is compulsory.

Schools and day-care
Pupils will still have to take Covid tests three times a week and, in classes where there are at least two children who test positive in the rapid antigen tests, then tests should be carried out daily for a week.  

Unlike in Brandenburg, there are currently no plans to move away from face-to-face teaching. The child-friendly ‘lollipop’ Covid tests will be made compulsory in day-care centres and parents will be required to confirm that the tests have been carried out. Day-care staff have to document the results.

What about vaccination centres?
Berlin wants to expand these and set up new ones, according to Matz. A new vaccination centre should open in the Ring centre at the end of the week and 50 soldiers from the German army have been helping at the vaccination centre at the Exhibition Centre each day since last week.

The capacity in the new vaccination centre in the Lindencenter in Lichtenberg is expected to be doubled. There are also additional vaccination appointments so that people can get their jabs more quickly. Currently, all appointments are fully booked well into the new year.
